2001 Aprilia Scarabeo 50 2T w/70cc Big Bore

When the scooter is started and on the centerstand, the clutch immediately engages and the rear tire is spinning at about 15mph. I lowered my idle speed to 1250rpm (1800rpm ‐ 100 normal) but it spins just as fast. The tire is hard to stop as well. I can not stop it with my hand, it will stop when I take it off the stand and put the tire on the ground but I can still feel the scooter going if I don't hold the brake. Clutch springs are brand new, new torque spring too. Im running 6.5g rollers. Are my rollers too light/heavy? I also have Malossi race exhaust, bigger 17.5mm carb w/air pod filter, Polini performance clutch, 1500rpm contra, 65% clutch shoe springs. Stock variator with shims installed for maximum belt/pulley use. Stock rear pulley and bell.
